Special processing: Multiband compression

- [Instructor] In this special techniques video…I want to show you about multi-band limiting…in very descriptive terms.…So, again, one of the biggest complaints…I get about compression is I'm using too much of it.…And one of the ways to avoid that…is with a high-pass filter…applied to the detection circuitry.…This LA-2A is a newer design that helps to…show us how that works very well.…This emphasis control puts a high-pass filter…at the input stage of the limiter…so that you can allow low frequency material…to skate through undetected by the gain-reduction circuitry…and only compress the upper end of the spectrum.…

So when it's fully rotated to the clockwise side,…full bandwidth is applied to the gain-reduction…detection circuitry, so watch what happens.…Look what's happening to the bass at full range.…(bassline)…Now that could result in some pumping for the bass…'cause it's compressing between five and seven dB.…And that could be too much.…But you want to really pronounce…the bass nicely in the top end.…

I'm sorry there's no indicator of the frequencies,…
